Review the subjects included, open and closed dimensions, hinge construction, panel material, and image technique. A travel diptych should close securely and protect its surfaces, while a larger triptych needs stable hinges and enough support to remain open. Confirm whether images are printed, mounted, painted, or mixed media.

Choose a set whose iconographic relationship supports its purpose, such as a home prayer corner, wedding, baptism, or feast. Check inscriptions and orientation before ordering. If the piece will travel, consider weight and a protective pouch. Keep folding icons dry and avoid forcing hinges beyond their intended angle.
